The vital role of Application Development or Functional Testing has been well stated. Nevertheless, in the situation of Application Modernization, the role increases, as it carries in its purview the challenges, risk, and scope for uplifting and upgrading the application. In a way, it also supports teams for authenticating the efforts.

Keeping this scenario in mind, we are presenting you with a list of three ways in which functional testing company helps in-app modernization.

1. Delivering the Anticipated Result

Functional Testing is required to discourse the apprehensions around the real application of functional needs. It is normally mentioned as black box testing, which does not require much information regarding the implementation procedure. With Functional Test sets, every situation becomes a functional test. Therefore, when a function is applied or presented within the app, the particular functional test is implemented after been unit tested. The significance of functional tests completely hinges on the objectives and priorities defined for the app. The objective is to distribute what is anticipated from the application.

2. Continuous Functioning and Anticipated Business Result from All the Functions

With System Testing the teams implement end-to-end functional tests across software units. This assists to guarantee that, as a whole, all the functions distribute anticipated business result. The emphasis is on the complete situation that requires critical units to fit in and distribute a specific activity. Therefore, all subsystems have to be verified primarily before they are combined with the additional subsystem. In order to circumvent any trouble in recognizing instant errors, the components are slowly integrated after being tested in separation.

This is very much pertinent in an Application Modernization situation, where the latest features are being entrenched, but these new mechanisms must assimilate with the current ones to deliver a unified experience.

3. Application Modifications Do Not Influence the Complete System

Regression Testing is essential to guarantee that the code alterations do not bring in glitches or bugs that might influence the general system. Therefore, it should include plans from the original unit that also comprises of functional as well as system tests. This would assist in explaining the present functionality that is anticipated from the application. Regression testing might not be needed for the entire system, but it might be required for specific functional areas that are complex in nature.

Nonetheless, the challenge comes in while modernizing legacy apps, where the development team has to deal with the hardcoded business procedure workflow and other firmly bound legacy codes.

A test case can be defined as the sets of variables and conditions utilized by the software testers to check if the system performs as per expectations. Test cases play a major role in authenticating the test coverage of a software app. It entails essential fields that offer information regarding the test case, the expected results, and the activities involved in the execution. These fields entail a different name, any requirement involved, detailed steps, input conditions, and desired outcomes for a specific app function.

Effective test cases are simple to maintain and execute. A test case management tool plays a significant role in streamlining the test case process. They make the testing procedure more effective by saving effort and time.

Keeping this scenario in mind we are providing the list of 10 best practices for developing test cases.

1. Keep It Easy to Understand and Simple

An effective test case is extremely simple and well-written for the testers to execute and understand. Organize the test cases as per related areas or specific categories of the app. Test cases can be grouped on the basis of their user story or modules like browser specific behaviors. As a result, it becomes easy to maintain and review the test document. Information provided in the test cases must clear to other developers, testers, and stakeholders.

2. Entail End User Perspective

Take into consideration, the end user perspective prior to drafting the test case. Put yourself in the shoes of an end user who is the main stakeholder for whom the app is created. You must the end user perspective, the functionality aspects to be covered and the requirement. This will assist in identifying test scenarios that rise in actual conditions.

3. Utilize Correct Naming Conventions

The test case must be named in a way that makes it easy for the stakeholders to understand and detect its objective. You should name the test cases in accordance with the functional area or the module that is included for testing.

4. Offer Test Case Description

An appropriate test case description will permit the users to comprehend what is being tested and how it is being tested. Provide pertinent details like any other particular information and test environment. Mention the testing tools and the testing data to be utilized to be applied for executing the tests.

5. Entail Preconditions and Assumptions

Testers must include all the conditions and assumptions that are valid for test cases. Give details related to the test environment, any special set up for the implementation of the test cases.

6. Mention the Steps That You Have Incorporated

Incorporate the actual steps included in the implementation of the test cases. Testers are not missed out on any step. Make sure that all the test case authentication steps are covered. Contain relevant screenshots or documents that can assist in the execution of the steps provided in the test design.

7. Provide Details of the Test Data

You should provide the test data details for test case execution, particularly in scenarios where the same data is used again. This assists in time-saving for the development of the test data for every cycle to be run. Mention the value range, for the particular fields. Testers must not try to test each and every value. The objective must be to ensure maximum coverage by selecting some from every class.

8. Make it Modular and Reusable

Testers must guarantee that there is zero conflict and dependency among the test cases. In a scenario, where test cases are batched or inter-dependent, you are advised to mention them clearly in the test document.

9. Assign Testing Priority

Testers must assign test priority to every test case based on the component or feature involved. This will guarantee that a high priority test case is executed first during the execution.

10. Offer Post Conditions and Desired Results

Testers are advised to include the expected outcome for each step of the test case. You can also entail relevant documents and screenshots for reference. Mention the things or post-conditions that must be confirmed after test case execution.
